60% is pretty low for PET, Glass isn't recycled perfectly either, but is generally better than PET.

In Switzerland 82% of PET is recycled. (Note that this number is the percentage that is really reused. Not the percentage that is collected.) The same number for glass is 96%. That means only 44% of glass gets recycled 20 times.

However, this is for reuse, not recycling. Not many glass bottles get reused, most get recycled. Recycling glass is less energy efficient than reusing.
